Among the grievous wrongs done by touchscreen technology, the worst is its disregard for tactile feedback. Without the pleasant sensation of a button being pressed, we are woefully incapable of using any gadget without complete visual attention. This Nokia concept tries to right this wrong by using a small pump to fill a substrate beneath the screen that gives our fingers something to feel and press.
